병렬성 및 동시성 동시에 구현하는 방법 질문드립니다.

안녕하세요. 멀티 프로세싱으로 병렬적으로 처리하면서 동시에 하나의 프로세스에서 멀티 쓰레드를 통해 동시적으로 처리할 수 있다고 강의에서 넌지시 말하시고 넘어가셔서, 혹시 파이썬으로 ProcessPoolExecutor안에서 ThreadPoolExecutor를 사용하려면 어떤식으로 코드를 짜야할까요??

순수한 DI 컨테이너 AppConfig에 @Configuration

미해결

스프링 핵심 원리 - 기본편

안녕하세요. 강의 후반부 스프링 없는 순수한 DI 컨테이너로 메서도 호출을 한다면, 계속해서 객체를 새로 생성하는 예시를 보여주는 부분이 있습니다. 여기서 궁금한 것은 AppConfig에 @Configuration 과 해당 클래스 메서드들에 @Bean 설정이 되어있는데, 이것들은 순수한 DI 컨테이너에서 의미없는 어노테이션들이 맞을까요? 원래는 빼야하는데 그냥 안빼시고 설명하신 것 인지 궁금합니다.

(nx ==7 && ny == 7) 일때 return 해줘야 하지 않나요?

미해결

자바(Java) 알고리즘 문제풀이 입문: 코딩테스트 대비

저는 아래와 같이 nx가 7이 될때 return을 해줘야 한다고 생각했습니다. 왜냐하면 distance 배열에서 거리를 입력하는데, 7,7에 도착하는 순간 return을 한 그 순간의 값이 최단경로의 길이라고 생각했습니다. return을 해주지 않는다면 distance[7][7]의 값이 최단 거리가 아닌 가장 긴 거리의 값으로 덮어써 진다고 생각을 했는데, 왜 (nx ==7 && ny == 7)경우 return 하게끔 예외처리를 해주지 않아도 되는지 궁금합니다. for (int i = 0; i < 4; i++) { int nx = x + dx[i]; int ny = y + dy[i]; // if (nx ==7 && ny == 7) { // distance[nx][ny] = distance[x][y] + 1; // answer = distance[nx][ny]; // return; // } if (nx >= 1 && nx <= 7 && ny >= 1 && ny <= 7 && board[nx][ny] == 0) { // 범위 안이고 해당 좌표의 값이 0 일 경우 board[nx][ny] = 1; distance[nx][ny] = distance[x][y] + 1; queue.offer(new Point(nx, ny)); } }

dashboard 2.0 설치 시 토큰값 생성이 안됩니다.

해결됨

대세는 쿠버네티스 (초급~중급편)

dashboard 2.0 설치중인데요 kubernetes-dashboard-token- -뒤에서 tab을 눌러도 자동완성이 안되고 동영상 학습과 같은 값을 임의로 넣어봐도 안됩니다. 어떻게 해야 할까요? tab은 수십번 눌러봤습니다. 맨 앞에 kubectl 부분에서 ctl 지우고 kube에서 tab을 누르면 자동완성이 나오는데 kubernetes-dashboard-token- 여기에서는 아무리 눌러도 자동완성이 안되네요

강의시간 11:26 위 상황은 jsession 쿠키를 제거한 상태에서 remember-me쿠키만 지닌채 서버로 요청한 상황입니다. jsession이 없기 때문에 securityContextHolder 에서 getContext() 로 찾을 수 있는 securityContext객체가 없기 때문에 getContext( )의 결과는 null 이지 않을까...? 위의 물음에 잘못된 점이 있는지 궁금합니다.

변수 상태유지

해결됨

ASP.NET core Blazor 디테일 강의 - 초급편

안녕하세요 오랜만에 학습하다 궁금한점이 있어 문의 남깁니다. razor 페이지에 변수를 선언해 해당 값을 화면에 보여주는 작업을 할 시 사이드바를 통해 다른페이지로 이동했다 돌아오면 변수가 없어지게 됩니다. 이를 해결하기 위해 클래스를 선언 후 해당 클래스를 종속성 주입을 통해 해당 클래스 내부의 변수를 사용하는 식으로 해결했는데 이 방법이 정석적인 방법인지 궁금합니다. cs파일의 클래스를 통해 함수를 구현하는데 해당 함수에서 다른 razor페이지에 직접 접근해 데이터를 화면에 뿌리는 방법이 있는지 궁금합니다. 현재는 방법을 찾지 못해 cs파일을 사용하지 않고 해당 함수 내용을 razor 파일의 code 부분에 해당 함수 내용을 구현해 사용하고 있습니다. 배열에 값을 입력하고 입력되는 값들을 화면에 보여주기 위해 StateHasChanged() 를 사용해 보여주었는데 해당 페이지에서는 잘 동작을 하는데 다른 페이지로 이동 후 다시돌아오면 StateHasChanged()가 작동하지 않습니다. 디버그 확인해보니 페이지를 이동했다 와도 배열에 값을 정상적으로 삽입이 됩니다. 다른 이벤트(버튼 클릭) 등이 발생하면 화면에 보여주는 작업이 동작하는데 StateHasChanged()로는 동작 안하는게 이해가 안갑니다... 디버그 모드로 확인 시 StateHasChanged를 수행하기는 하는데 화면에는 변화가 없습니다. 이런경우가 있나요? 항상 감사합니다.

스프링 역사 (부트 버전) 질문!

(예) [질문 내용] 안녕하세요 김영한님! 강의 항상 잘듣고 있습니다! 다름이 아니라, 스프링 역사이야기를 듣다보니, 궁금해져서 아래 링크(스프링부트 페이지)로 확인해보았습니다. https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.7-Release-Notes 그러던중, 현재 스프링부트는 2.7 까지는 안정적이게 나와있는 것을 확인하였고, preview 로 3.0 버전이 나온것 까지는 알게 되었습니다. 하지만, 여기서 궁금했던것은 v2.7 다음 버전이 v2.8이 아닌 v3.0인것으로 보이는데, 이게 왜 이렇게 뛰는 것일까요? , 기존 spring boot 2.X -> Spring boot 3.X 변경되는 점이 많아서 그런건가요?

리스트의 복사에 관해 궁금한게 있는데요

해결됨

[C#과 유니티로 만드는 MMORPG 게임 개발 시리즈] Part1: C# 기초 프로그래밍 입문

안녕하세요 루키스님. 강의 잘보고 있습니다. 보다가 의문점이 드는게 있어서요. public List<Item> item = new List<Item>(); 이런 리스트가 하나 있다고 했을때 Item items = item[0]; 이렇게 할 경우 이게 얕은복사인가요? 아니면 참조에 해당되는건가요? 저 상태에서 items 를 수정하니 원래 리스트에 있던 item[0] 의 값도 같이 바뀌더라구요. 얕은복사 = 참조 처럼 제가 알고 있는데 다른건지.. 그래서 이걸 객체? 를 새로 생성하는 걸로 다르게 해볼려고 public Item DeepCopyitem() { Item copy = new Item(); copy = item [0]; return copy; } return이 함수에게 값을 반환하는거니까 이렇게 하면 새롭게 생성이 될줄 알았는데 여전히 copy가 원래 있던 리스트의 값을 같이 수정해버리는겁니다.. 그래서 그 후에는 아예 public Item DeepCopyitem() { Item copy = new Item(); copy.값 = item [0].값; copy.값2 = item [0].값2; copy.값3 = item [0].값3; copy.값4 = item [0].값4; copy.값5 = item [0].값5; return copy; } 이런식으로 하니까 그제야 원본에 있던 리스트 값이 수정이 되질 않더라구요.. 근데 값이 막 수백개씩 되는데도 저렇게 하는게 맞는건지..? 저게 깊은복사가 맞는건지..? 검색을 해봐도 이렇다할 정보가 나오질 않아서 헷갈립니다.. 제가 복사나 참조 개념을 헷갈리는걸까요? 또, 저런식으로 노가다..처럼 값을 넣어서 새롭게 객체를 만드는게 맞는 방법인가요?

왜 Dto에 @Data가 빠지면 이런 오류가 나는 지 궁금합니다. 강의에서는 getter가 없어서 오류가 났다고 배웠습니다. property가 없다고 오류가 난다고 배웠는데 왜 getter가 있어야 하는 지 궁금합니다.
